IMPROVEMENT IN CHRONlATIC-PRINTING PRESSES.

Specification forming part of Letters Patent No. 134,579, dated January7, 1873.

To all whom it may concern:

Beit known that I, GEORGE W. WooDsIDE, of the city of PhiladelphiaJ andState of Pennsylvania, have invented certain Improvements in Ohromat-icPrinting Presses for printing druggists and other labels, of which thefollowing is a speciiication:

My invention consists mainly of the following particulars: A verticallyreciprocating bed-plate, operated by means of cranks andconnecting-rods, is provided with an adjustable platen orimpression-plate, which is combined with the type-form connected with atop plate of the machine. The said bed-plate is provided at one end withfeed-rollers,

which have an intermittent motion imparted to them by a ratchetmovement, and at the other end a gum-trough and distributin g-roller forgumming or pasting the under side ofthe labels. The type-inking rollerreceives its movement by means of a lever-connection at its ends withthe bed-plate, whoseup-and-down movements cause it to pass under theinkin gcylinder and back under the form for spreading the ink thereon.The inking cylinder takes the different-colored inks from a series ofdistributing-rollers whose peripheries have divided sections for thediii'erent colors. These distributing-rollers have a vibrating motion inline with their axes, imparted by means of cams formed on the ends ofthe inking-cylinder, with which annular guides on the rollers areconnected.

The construction and operation of the machine are hereinafter fullydescribed.

Figure l is a plan view of the improved press. UFig, 2 is a side view ofthe cylinder L. Figs. 3 and 4 are plan and edge views of the bed-plateE. Figs. 5 and (i are like views ofthe platen D. Fig. 7, Sheet No. 2, isa front elevation of the press. Figs. 8 and 9 are side and edge views ofone of the levers O. Figs. 10 and ll are like views of one of theguide-strips F. Fig. l2, Sheet No. 3, is a rear elevation of the press.Fig. 13 is an end elevation.

Like letters in all the figures indicate the same parts.

A A represent the housings of the standing frame. B is the top plate, tothe under side of which the form C is connected by means of thepermanent rabbeted strips a a, as seen in Fig. 7. D is the platen orimpression-plate in the movable bed-plate E, upon which the paper to beprinted is laid and carried forward during the printing operation, therebeing guide-strips F F, adjust-ablelby means of the cross-slots b andcontining-screws c, in adaptation to different widths of paper. Thebedplate is provided with vertical screws d for regulating the height ofthe platen, as seen in Fig. 7. The platen and bed-plate are representedin detail in Figs. 3 to 6, inclusive. The bed-plate is connected withthe horizontal shaft G by means of the crank-arms e e of the latter andconnectingrods H H. The shaft G is revolved for elevating and depressing the bed-plate E by means of the drivingshaft l, with which it isgeared by means of the wheel J and pinion J. its up-and-down movement,slides on the vertical rods A Al A A', there being vertical holes in itwhich correspond to the diameter of the rods. The rods are connected attheir lower ends to the housings A A, and at their upper ends to the topplate B.

At the rear side ot' the press there are distributing-rollers K K K andinking-cylinder L, whose journals turn in the vertical supports f f,that have a permanent connection with the housings A A and top pla-te B.M is the inking-roller, which has a forward-andbackward motion given toit to bring it alt-ernately into connection with the' inking-cylinderand the type-form by the upland-down movements of the bed-plate E, `bymeans of the p connecting-rods N N, the levers O O on the rock-shaft P,and the horizontal levers Q Q.. The inking-cylinder is held up againstthe form C as it passes under the same, by means of the rods It R andsprings S S, connected with the rear ends of the levers Q Q and the armsg g of the levers O O, as seen in Figs. l2 and 13.

Springs have been used heretofore for keeping the roller against theform without the use of rods. tion with the springs for the purpose ofpreventing the falling of the roller, in the event X of the springsbreaking, until the pressman has noticed their breaking and suppliedtheir Vplaces with new springs.

The bed-plate, in v I employ the rods in combinavmovement of thebedplate.

.ment of the bed-plate, and the pinion Y, con- The inking-cylinder isrevolvedby means of the belt h, which connects With the pulley l, on oneend of its shaft, and the pulley'f on the driving-shaft I, seen clearlyin Figs. l2 and 13. The cylinder is provided with cams t', Fig. 2, onits ends, which act against the annular guides j on thedistributing-rollers, whereby a vibratory motion is given to the latterin line with their axes for the more perfect distribution of the ink.

The inlring-rollers may be divided in sections corresponding to thesections of the distributing-rollers, if desired.

The sheets on which the labels are printed are unwound at one end of themachine as the printing operation progresses. They pass between thehorizontal guide-strips F F above described.

There are shafts T T geared together by means of the wheels U U', whichare provided with feed-rollers V., The rollers are adj ustable on theirshafts for the purpose of being so arranged, when desired, as to feed aplurality of strips of paper at one operation, to receive differentlyfrom each other the colors from the inkingroller. An intermittent motionis given tothe rollers so as to .keep the paper stationary when theimpression is -being given, and move it forward during the intervals bythe up-and-down movement of the bed-plate E, there being on one end ot'the lower feed-wheel shaft T a disk, XV, provided with a sprin gdetent,lc, which engages with the ratchet-wheel X and prevents its turning onthe shaft in the downward movement ofthe bed-plate. There is a pinion,Y, fast to the ratchet-wheel, and, in connection with the pinion, atoothed segment, Y', which turns partially on the permanent arm l thatprojects from the bed-plate. There is an arm, l', connected with thesegment which has a joint-connection with the vertical rod m, whoselower end is jointed to the `bracket u attached to the frame, so that asthe bed-plate is descending the inner end of said arm is turned upward,giving a partial turnto the segment, which, by turning ihe pinion Y,gives motion to the feed-rollers to'feed the paper forward in thedownward The spring-detent 7c does not operate in the upwardAmovesequently, turns loose on the shaft T, and thus prevents themovement of the rollers during the impression. The arm Z is providedwith a series of pin-holes, o, for the adjustment of the vertical rod mtovary the length of feed of the paper, as may be required.

It will be seen that the paper is fed through the machine at rightangles to the line of niotion of the inking-rollers, whereby there ismuch lesscomplication than would beby feeding in the line of the motionof the rollers, as in this case only one roller is required forspreading the ink on the form, while in the other arrangement one rolleris required for each color.

The advantage does not extend only to decreasing the expense of buildingthe machine, but also makes a great saving of ink by not having it tocover a great number of rollers, it being necessary to wash' the rollersat intervals in order to insure the execution of good work. v v

The length of feed ofthe paper is equal to each color on the form, sothat an impression of all the colors is given in the passage over thcbed-plate. There are tapes 19 connected at one end with the horizontalrod q at one edge of the bed-plate E, and at their other ends to pins rat the other edge, to prevent the paper s being drawn up from .theplaten as the latter descends. Pins r may be used instead of the rod q.There is a gum-trough in connection with the right-hand end of thebed-plate, in which is situated aroller, Z ,which gums or pastes theunder side of the paper as it passes over it, the roller being turned bythe forward movement ofthe paper. The paper is unwound from a rollerassit passes through the press, and is conveyed away from the latter, asit is printed and gummed, by any suitable device.

I do not claim the combination of the platen and hiking-roller and theoperating mechanism as set forth in the patent ot'T. H. Dodge, datedNovember 18, 1851; but

Vhat I claim as new, and desire to secure by Letters Patent, isv l. Thecombination of the rods N N,.levers 0 0, and connecting rock-shaft P,lever Q, and springsSwith the vertically-movingbed-plate E andinking-roller M, substantially in the manner and for the purpose setforth.

2. The cams t' on the ends of the cylinder L, in combination withtheannular guides j of the distributing-rollers K K K, for giving avibratory motion to the rollers in the line of their axes, substantiallyas described.

The combination of the feed-rollers V with the shafts T and T adjustablethereon, and with the ratchet-feed, for the purpose ot' feeding aplurality of strips at the same time, substantially as described.

4. The combination of the paste-trough Z and cylinder Z with thebed-plate E, as and for the purpose set forth.
